Mozilla is seemingly ramping-up its development schedule, amidst suggestions that Firefox 5 will officially launch tomorrow.
There aren't expected to be any GUI enhancements over what we saw in Firefox 4, but it's said that - as expected - the latest iteration will focus on bug-fixes and deliver improved performance and stability. Adding to features such as a built-in PDF reader, there's also improved HTML 5 support and a Do-Not-Track option - disabling the ability for advertisers to track browsing habits.
Word also has it that Mozilla is aiming to keep up with Google's ravenous development pace, meaning that Firefox may reach the heady heights of version 8, in time for Christmas.
